Huge win for car owners! All TSBs to be made public.
The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues.
Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

when you have your foot on the gas it shakes at low speeds and goes away at faster speeds, sometimes it doesn't do it at all but it seems like a vibration in the right side of the car, had it looked at by a mechanic and he said he thought it was an axle or a tie rod, he was wrong.

Impala LS 3.8L V6

Automatic transmission

the transmission had acted up in the past 6 months or so but stopped. I decided to change the fluid and filter. it was ok for a day. it started randomly shifting hard into gear at part throttle. the car would shake and vibrate as though it was not engaging the clutch properly. at times it felt like it was shifting too soon causing the engine to bog down. I took it to a auto parts store and the code was P0742 (TCC circuit stuck on). after checking the internet I was expecting a repair around $1000 to $2500/$3000. the higher cost would be if it had to be replaced or rebuilt. there are places online that will charge $1000 for a new/rebuilt transmission and will ship it to the shop of your choice. I had considered that instead of a dealer or transmission shop as everyone knows of the horror stories of trans shops and dealer repair costs to transmissions.

fortunately it appears to be fixed now and supposedly has a 12 month/12,000 mile warranty for what that is worth. (my luck it would be another internal part) the receipt showed about half of the cost was parts. I know the parts are not that expensive but it is somewhat labor intensive.

the car was shaking and it was taken to the dealer and they couldn't find anything wrong with it, they only found codes in the computer regarding the transmission a month later it was taken to Meineke and they couldn't even fix the problem it had to be taken to a specialist. Now i find out that it might be the catalytic converter.
